Installing Courier POP and IMAP

Courier IMAP

1. 編譯安裝

   bunzip2 courier-imap-3.0.3.tar.bz2tar xvf courier-imap-3.0.3.tar or [root@linuxas3 src]# tar jxvf courier-imap-3.0.3.tar.bz2 [root@linuxas3 src]# cd courier-imap-3.0.3 su other [root@linuxas3 courier-imap-3.0.3]# su chen [chen@linuxas3 courier-imap-3.0.3]$./configure --with-redhat \ --disable-root-check --enable-unicode=utf-8,iso-8859-1,gb2312,gbk,gb18030 \ --with-trashquota --with-dirsync [chen@linuxas3 courier-imap-3.0.3]$ make [chen@linuxas3 courier-imap-3.0.3]$ make check su root [chen@linuxas3 courier-imap-3.0.3]$ exit exit [root@linuxas3 courier-imap-3.0.3]# make install [root@linuxas3 courier-imap-3.0.3]# make install-configure [root@linuxas3 courier-imap-3.0.3]# cd /usr/lib/courier-imap/etc/

2. /usr/lib/courier-imap/etc/authdaemonrc

   [root@linuxas3 etc]# vi /usr/lib/courier-imap/etc/authdaemonrc authmodulelist="authmysql" authmodulelistorig="authmysql" version="authdaemond.mysql"

   #authmodulelist="authcustom authcram authuserdb authldap authpgsql authmysql authpam"

   去掉不需要的模組，否則會驗證失敗。

3. /usr/lib/courier-imap/etc/authmysqlrc

The fixed string will # be used to do an UPDATE operation on database. In other words, it is # used, when changing password. # # There are four variables, which you can use. Substitution will be made # for them, so you can put entered username (local part) and domain name # in the right place of your query. There variables are: # $(local_part) , $(domain) , $(newpass) , $(newpass_crypt) # # If a $(domain) is empty (not given by the remote user) the default domain # name is used in its place. # $(newpass) contains plain password # $(newpass_crypt) contains its crypted form # # MYSQL_CHPASS_CLAUSE UPDATE popbox \ # SET clearpw='$(newpass)', \ # password_hash='$(newpass_crypt)' \ # WHERE local_part='$(local_part)' \ # AND domain_name='$(domain)' # [root@linuxas3 etc]#

4. 編輯pop3d檔案，將POP3DSTART=NO改為POP3DSTART=YES

   [root@linuxas3 etc]# vi pop3d POP3DSTART=YES

5. 編輯imapd檔案，將IMAPDSTART=NO改為IMAPDSTART=YES

   [root@linuxas3 etc]# vi imapd IMAPDSTART=YES

6. 啟動POP，IMAP

   /usr/lib/courier-imap/libexec/pop3d.rc start /usr/lib/courier-imap/libexec/imapd.rc start

7. 測試POP，IMAP
